Help please

Answer:

[tex]x < - 21[/tex]

Step-by-step explanation:

1. Multiply both sides by 3.

[tex]x < - 7 \times 3[/tex]

2. Simplify 3 × 7 to 21.

[tex]x < - 21[/tex]

therefor, the answer is x < -21

Answer:

x=-10

Step-by-step explanation:

-3(x+7)=9

-3x-21=9

add 21 to both sides of equation

simplify divide both sides by like terms

simplify again and you have your answer

Step-by-step explanation:

1. the rate of change is constant. the slope is 3

2. the rate of change is variable, because it's not consistent.

Answer:

y = 2

Step-by-step explanation:

m = (2 - 2)/(6 - (-6))

m = 0

there's no slope, so it's just 2

As you can see the 2 points have the same y coordinate that means the line passing through it is going to be a horizontal line with a consistent y level of -2.

The equation will be just what I said y=2

Hope this helped!

Answer:

Step-by-step explanation:

For a function to have an inverse, it has to pass the horizontal and vertical line test, yes both of them. This function does, so we can continue. The first step for finding an inverse is replacing f(x) with y. Then switch the places of x and y.

[tex]x=\sqrt{y-1}[/tex]

Now the next step is to solve for this new y value, which is equivalent to f^-1(x). Square both sides to get rid of the radical.

[tex]x^2=y-1[/tex]

Add 1 to both sides and that is your inverse function

[tex]y=x^2+1[/tex]

Answer:

3

Step-by-step explanation:

To find the average rate of change, we can use the formula: (y2-y1) / (x2-x1).

Let (15, 45) be (x1, y1) and (29, 87) be (x2, y2).

So we have: (87-45) / (29-15)

This can be simplified to: 42/14, or 3.

Answer:

9) 5/10

10) 4/5

Step-by-step explanation:

A terminating decimal is a decimal that stops eventually

2/3 = 0.6666666...

5/6 = 0.833333...

5/10 = 0.5

6/9 = 0.6666666...

5/10 has a result of a terminating decimal

8/9 = 0.888888...

1/7 = 0.142857...

4/5 = 0.8

4/11 = 0.36363636....

Answer:

Step-by-step explanation:

35 divided by 7 is 5. 3,500 is 35 x 100. 35 hundreds (3,500) divided by 7 is 5 hundred (5 with 00 at the end). 3,500 divided by 7 is 500.

Actually Welcome to the Concept of the Surface areas and Volume.

Since Box A is cube, it's volume is Side^3

hence taking the cube root of 512 , we get as,

Side length of Box A is 8 m.

hence diving 8/2 = 4 m

4 m is a side of Box B.

hence, Volume of Box B is = (4)^3 = 64 cubic metres.

Vol. Box B = 64 m^3

Answer:

The correct answer is D: 64 meters cubed

Step-by-step explanation:

You can take any example but let's say 128 times 2 times 2 which equals box A, now you must divide all dimensions by 2 and you will get 64 times 1 times 1 which adds up to 64, this will work with any example.

Answer:

x=37, Angle A is 74. Exterior angle B is 185

Step-by-step explanation:

I'm pretty sure this right but This is a triangle that is folded to the inside. This means that most likely there is a negative interior degree

angle. Using the interior theorem, we can add up all the non adjacent sides to find the exterior angle of the adjacent side. 79+2x+32=5x, 2x+111=5x, 111=3x, x=37. Then plug 37 in for x Angle A is 74 degree and B exterior angle Is 185 degree.

Answer:

(-4,1)

Step-by-step explanation:

The answer is just where the two lines intersect

I'm rather tired so double check me on this but I'm getting about (-4,1) and it's asking for an approximation so think (-4,1) is fine

Answer:

It's around (-4. 5, 1.5). It's somewhere in that range.

Step-by-step explanation:

Given \:number (m) = £ 490Givennumber(m)=£490

Increase (g) = 11\%Increase(g)=11%

\begin{gathered} \red{ Required \:number } \\= m\Big( \frac{(100+g)}{100} \Big)\\= 490\Big(\frac{100+11}{100}\Big)\\= 490 \times \frac{111}{100} \\= 490 \times 1.11 \\= £ 543.9 \end{gathered}

Step-by-step explanation:

You have to add 2 and nothing

Answer:

Because they are both negative that means they are on the left side so -0.4 is closer to the 0 so less.
